ANN: ConfigObj 4.3.0
by Fuzzyman April 7, 2006

April 7, 2006

`ConfigObj 4.3.0 <http://www.voidspace.org.uk/python/configobj.html>`_ is now released. This has several bugfixes, as well as *several* major feature enhancements. You can download it from : `ConfigObj-4.3.0.zip 244Kb <http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=configobj-4.3…>`_ .. raw:: html {title;What is ConfigObj ?} **ConfigObj** is a simple but powerful config file reader and writer: an *ini file round tripper*. Its main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files. It has lots of other features though : * Nested sections (subsections), to any level * List values * Multiple line values * String interpolation (substitution) * Integrated with a powerful validation system - including automatic type checking/conversion - repeated sections - and allowing default values * All comments in the file are preserved * The order of keys/sections is preserved * No external dependencies * Full Unicode support * A powerful ``unrepr`` mode for storing basic datatypes .. raw:: html {title;What's New ?} Moved the tests and the CHANGELOG (etc) into a separate file. This has reduced the size of ``configobj.py`` by about 40%. Added the ``unrepr`` mode to reading and writing config files. Thanks to Kevin Dangoor for this suggestion. Empty values are now valid syntax. They are read as an empty string ``''``. (``key =``, or ``key = # comment``.) ``validate`` now honours the order of the configspec. Added the ``copy`` mode to validate. Thanks to Louis Cordier for this suggestion. Fixed bug where files written on windows could be given ``'\r\r\n'`` line terminators. Fixed bug where last occurring comment line could be interpreted as the final comment if the last line isn't terminated. Fixed bug where nested list values would be flattened when ``write`` is called. Now sub-lists have a string representation written instead. Deprecated ``encode`` and ``decode`` methods instead. You can now pass in a ConfigObj instance as a configspec (remember to read the configspec file using ``list_values=False``).

RPyC 2.45 released
by tomerfiliba＠gmail.com April 7, 2006

April 7, 2006

what's RPyC: Remote Python Call (RPyC) is a python library that provides transparent and symmetrical distributed computing and remote procedure calls. site: http://rpyc.sourceforge.net what's new: this is a maintenance version of RPyC (Remote Python Call). * cleanups * fixed a bug with PipeStream.write * added stubs for Stream.wait and Stream.is_available to the windows version, so PipeConnection now works on windows as well. * added optional authentication: auth_server.py, and a new factory - AuthSocketConnection. see demo below. why add authentication? many people wanted to run rpyc over the internet, but it's a huge security risk. now the connection itself is not encrypted, but the server will require a login before it creates the connection. you are still encouraged to use SSL/VPNs where available, as it's surely more secure. also, please report security risks with my algo if you find any. demo: # run auth_server.py, then do from Rpyc import AuthSocketConnection conn = AuthSocketConnection("yossarian", "catch22", "localhost") # from this point it's the same -tomer

Construct 1.20 released
by tomerfiliba＠gmail.com April 7, 2006

April 7, 2006

what is Construct? Construct is a library for declaratively defining data structures at the bit-level, with lots of "built-in" constructs. website: http://pyconstruct.sourceforge.net note: the code is getting pretty stable already, so dont expect any more frequent releases. what's new? * added Formatted, a construct that uses the built-in struct module. * added [Big/Little]Float[32/64], both parsing and building, using Formatted * added FlagsAdapter (see example below) * improved Flag, the constructor now takes 'inverted' instead of 'truth' * improved LV, and made PascalString use LV instead * removed PascalStringAdapter * removed the utils package (may be re-added later if i find what to put in it) example: say you have a 32-bit integer that holds flags, but splitting it up to a Struct of Flag's is difficult, because of byte-ordering, etc. the new FlagsAdapter lets you do the following: my_flag = FlagsAdapter( ULInt32("flags"), dict( owner_read = 0x0001, owner_write = 0x0002, owner_execute = 0x0004, group_read = 0x0008, group_write = 0x0010, group_execute = 0x0020, other_read = 0x0040, other_write = 0x0080, other_execute = 0x0100, ) ) >>> print my_flag.parse("\x83\x00\x00\x00") Container: group_execute = False group_read = False group_write = False other_execute = False other_read = False other_write = True owner_execute = False owner_read = True owner_write = True -tomer

RELEASED Python 2.5 (alpha 1)
by Anthony Baxter April 5, 2006

April 5, 2006

On behalf of the Python development team and the Python community, I'm happy to announce the first alpha release of Python 2.5. This is an *alpha* release of Python 2.5, and is the *first* alpha release. As such, it is not suitable for a production environment. It is being released to solicit feedback and hopefully discover bugs, as well as allowing you to determine how changes in 2.5 might impact you. If you find things broken or incorrect, please log a bug on Sourceforge. In particular, note that changes to improve Python's support of 64 bit systems might require authors of C extensions to change their code. More information (as well as source distributions and Windows installers) are available from the 2.5 website: http://www.python.org/2.5/ The plan from here is for a number of additional alpha releases, followed by one or more beta releases and moving to a 2.5 final release around August. PEP 356 includes the schedule and will be updated as the schedule evolves. The new features in Python 2.5 are described in Andrew Kuchling's What's New In Python 2.5. It's available from the 2.5 web page. Amongst the language features added include conditional expressions, the with statement, the merge of try/except and try/finally into try/except/finally, enhancements to generators to produce a coroutine kind of functionality, and a brand new AST-based compiler implementation. New major modules added include hashlib, ElementTree, sqlite3 and ctypes. In addition, a new profiling module cProfile was added. A large number of bugs, regressions and reference leaks have been fixed since Python 2.4. See the release notes for more. Enjoy this new (alpha!) release, Anthony Anthony Baxter anthony(a)python.org Python Release Manager (on behalf of the entire python-dev team)

The "Need for Speed" Sprint, Reykjavik, Iceland, May 21-28, 2006
by Steve Holden April 4, 2006

April 4, 2006

EWT LLC and CCP h.f., having specific commercial interests in doing so, have decided to sponsor a sprint on the Python programming language with specific short- and medium-term acceleration goals. The sprint is also intended to stimulate broad consideration of the future of Python, and specifically to try and identify the most promising routes to improved performance. Selected members of the Python developer community will receive direct invitations, and their attendance will be sponsored, to try to ensure the most effective possible result. In the spirit of open source events the sprint is open to all. The venue is the Grand Hotel, Reykjavik, http://www.grand.is/. The following objectives are of interest to the sponsors. * Improving the decimal module by implementing portions in C * Investigate whether RPython offers sufficient speedup over the regular CPython interpreter to replace tailored C and C++ code in MMP gaming applications * Implement an ordered dictionary in both C and Python * Implement data-structure-specific algorithms, which rely heavily on certain data structures, as RPython * Adding an iterator interface (similar to re.finditer) to the struct module * Further refine the PyPy LLVM back end to improve general execution speeds * Offer the PyPy team a sprint venue to continue their development work on Python implementations written in Python * Create a string subtype that provides lazy slicing without copying Sprinters are, as always, free to choose the aspects of Python they choose to work on. Flights should be booked to and from Keflavik airport (KEF). There will be a mid-week “let your hair down” social event to which all sprint participants are cordially invited. In order to ensure that sufficient meeting space is available, please notify Steve Holden of your intention to attend by emailing steve(a)holdenweb.com. regards Steve -- Steve Holden +44 150 684 7255 +1 800 494 3119 Holden Web LLC/Ltd www.holdenweb.com Love me, love my blog holdenweb.blogspot.com

ANNOUNCE: wxPython 2.6.3.2
by Robin Dunn April 4, 2006

April 4, 2006

Announcing ---------- The 2.6.3.2 release of wxPython is now available for download at http://wxpython.org/download.php. This is a mostly bug fix release and takes care of several "unfortunate features" discovered in the 2.6.3.0 release made last week. A summary of changes is listed below and at http://wxpython.org/recentchanges.php. What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module that wraps the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.2+, in most cases the native widgets are used on each platform. Changes in 2.6.3.2 ------------------ Fixed reference leak in wx.gizmos.TreeListCtrl.GetSelections. wxMSW: Fixed sizing issue with wx.Choice and wx.ComboBox. This change was implemented by reverting a prior fix for a different problem (continuous painting/resizing when a combobox is used as a widget in a wx.html.HtmlWindow) so a method to fix both problems is still being investigated. wxGTK: Fixed potential buffer overrun when pasting from the clipboard. Fixed problem in wx.lib.splitter when used on 64-bit platforms. Used the current length of the list for specifying an append instead of sys.maxint. wxMSW: Support added for XP themed owner drawn buttons and bitmap buttons. For example, if you change the foreground color of a button it will now be drawn with the XP themed style rather than an ugly generic button style. XRCed: Fix for Copy/Paste objects with international characters. Fixed the equality and inequality operators for some of the basic data types (wx.Point, wx.Size, wx.Colour, etc.) to no longer raise a TypeError if the compared object is not compatible, but to just return a boolean as expected. For example:: wx.Colour(64,0,64) == 123 ==> False wxMSW: Fixed (again) sizing/positioning issues of calling Realize on a wx.ToolBar that is not manaaged directly by a frame and that is already shown. wxMSW: Fixed wx.Choice/wx.ComboBox so they send events when a new item is selected only with the keyboard. -- Robin Dunn Software Craftsman http://wxPython.org Java give you jitters? Relax with wxPython!
